I would say that most home sew-ers don’t use much tailors chalk, because generally we use paper patterns that are pinned to the fabric, not cardboard patterns that need tracing around.
I would also say that most home sew-ers don’t like using tailors chalk, mainly because it’s hard to get a fine line. There are occasions where you need to draw straight onto the fabric, but given a choice the preference is for a chalk wheel with powder, or pencil.
Almost every small factory or studio I’ve worked in uses tailors chalk. As a factory junior at one of my very first jobs, I remember my heart sinking when I discovered I had to use tailors chalk. However, someone showed me how to best use it and I got used to it.
Even with regular sharpening, a square piece of chalk can last a long time, provided you don’t drop it and break it. One piece will mark out up to 100 garments.
The favoured colours are yellow and white, because they show up on almost any fabric. Use red or blue with caution; they can be impossible to remove from some fabrics so use them only when nothing else will work…..or else use biro or texta and live dangerously. It’s only fabric!
